Alex Chatburn1*, Kurt Lushington1 and Mark Kohler2 1 University of South Australia, Centre for Sleep Research, Australia 2 University of South Australia, Centre for Sleep Research; Cognitive Neuroscience Laboratory, Australia The influence of sleep on the consolidation of memory is now firmly established in the literature, and we are currently seeing the emergence of a new wave of models of sleep and memory. These are models of sleep's facilitation of associative memory, and deal with the processes through which sleep can flexibly and dynamically consolidate new memories into existing neural networks for the continued environmental adaptation of the individual. Sleep and associative memory is an emerging field, and there has never before been an attempt made to systematically analyse the literature. We systematically reviewed the published literature concerning types of associative consolidation as put forth in several recent reviews to determine i) if there is reasonable published evidence to support the existence of a relationship between the proposed associative processes and sleep, ii) to determine which sleep physiological events and states impact these processes and iii) to quantify the effect of sleep and sleep electroencephalographic (EEG) phenomena on these processes through meta-analysis. We have analysed the results of 21 studies which report on the effects of sleep relative to wake in regards to associative memory in healthy adults. Our results indicate a moderately large effect of sleep in facilitating associative memory behaviourally, although studies which have measured sleep physiology have reported a mix of findings. Significant correlations between sleep physiology and outcome appear to be based largely on mode of acquisition. We interpret these findings as supporting recent, reactivation based models of associative processing.
